Hi Folks,
I am trying to create a conference enviorment for the following requirement
1.)accepting calls from n no of b-party in such a manner that the voice
from b-party is heard to all the users in the conference and vice versa.
2.)making calls from a-party to n-users in such a manner that the voice
from a-party is heard to all the users in the conference and vice versa.
i have gone through confsample.c to get an idea.However i am successful in
registering my account to my sip server but when i try to do
pjsip_conf_add_port
in my code i get the following error....
